PRINCETON, N.J.--(BUSINESS WIRE)--Celator Pharmaceuticals today announced positive survival analyses from two completed clinical trials of CPX-351 (cytarabine:daunorubicin) Liposome Injection in acute myeloid leukemia (AML). A subset analysis of data from a randomized Phase 2b study in AML patients in first-relapse showed that patients with an unfavorable risk profile had significantly improved survival after treatment with CPX-351 compared to standard salvage therapies (ASCO Abstract 6525). Results from a second randomized Phase 2b study in elderly patients with newly diagnosed AML suggested that survival in patients with CRi (complete response with incomplete recovery of neutrophils or platelets) was similar to CR (complete response with complete recovery of neutrophils and platelets) (ASCO Abstract 6601), an effect usually not seen with standard treatment. The clinical findings were presented at the American Society of Clinical Oncology (ASCO) Annual Meeting, Chicago, IL, June 1-5, 2012.
